The PEN E-PL9 features a tried and tested (we could also say 'ageing') 16MP Micro Four Thirds sensor that we’ve seen in numerous Olympus cameras in recent years – as we felt when reviewing the OM-D E-M10 Mark III, a boost in resolution to 20MP would have been welcome. This camera does, however, get the latest TruePic VIII processor (also used in the flagship OM-D E-M1 Mark II), with an ISO range running from 100-25,600.
Rather than 1080p Full HD video capture, the PEN E-PL9 gets upgraded to 4K video capture at up to 30fps, while you can also shoot Full HD footage at up to 60fps.
